The introduction of Infrastructure as Code or IaC has transformed the way you can provision and deploy high-performance cloud-based IT infrastructures. IaC tools, such as , have been integrated into DevOps toolchains, saving DevOps IaC teams from the excessive manual effort. Terraform While these tools undoubtedly help accelerate building IT infrastructures, their limitations can impact DevOps’ ability to optimize and improve control of their IaC processes supporting future business needs. In this article, you’ll learn about IT infrastructure limitations that IaC DevOps teams deal with on a daily basis and how Spacelift is able to get past them. 1) Workflow One of the most frequent challenges while using more generic IaC tools is the driven by its reliance on pull requests. Some solutions offer multiple workspaces, but the result can be fragile and nondeterministic. non-intuitive workflow Since there’s no concept of mapping projects to branches or tags, anyone commenting on an approved pull request can deploy arbitrary code to production, even if the approval was meant for a short-lived experimental environment. . It is mostly driven by push and tag events, so building a sophisticated Git flow is much easier. Spacelift reports the outcome of its jobs as commit status checks, allowing you to block merging the code on a failing Spacelift check. Spacelift does not depend on pull requests Triggering a run can be customized using . Thanks to that, Spacelift can provide the same level of comfort and security to teams using one project per repository and those using mono repo with hundreds of interdependent projects. Git push policies 2) Access Control The majority of generic tools don’t offer access control models but rely on comments on pull requests to drive infrastructure deployments. While it is usually fine when a single repository drives a single Terraform project, it becomes a huge liability for more complex scenarios. Spacelift ships with a sophisticated mechanism (and under what circumstances) and what their to each of the managed projects should be. Even our can be subject to policy controls, allowing an admin to grant access to a project (think team, channel, user, etc.). allowing administrators to declare who can log in level of access Slack integration based on Slack-specific data 3) Policy Framework One thing that’s not in scope for most IaC solutions is the way to ensure that your infrastructure is compliant with industry best practices and your company policies. Spacelift puts in the center of its value proposition and builds a consistent, on top of . Apart from providing a comprehensive automated change review and ensuring compliance of your , Spacelift uses the same approach to allow you to declare rules around the and , , and , and creating . policy-as-code robust policy framework Open Policy Agent Terraform changes account project access handling push notifications starting runs triggering tasks relationships between projects 4) Complex Workflows Handling interdependencies between projects has always been Terraform’s Achilles’ heel. The usual approach to this problem is adding another layer of abstraction in the form of a Terraform wrapper like . But it’s only a partial solution as it breaks the problem into smaller chunks. Terragrunt on the other hand provide a smart, declarative automation layer on top of vanilla Terraform. They allow you to plug into state changes of individual projects and declare dependencies that should be resolved, following the changes that have just been applied.

Spacelift’s trigger policies 5) Private Module Registry Another problem to solve externally when using some of the generic tools is authoring and maintaining reusable T for your organization. Terraform is flexible in allowing modules to come from , but ensuring confidential access, as well as testing and versioning, are left to you, the user. erraform modules various sources Until now, the golden standard in that regard has been the . But Spacelift offers much more. Far from being just a glorified package manager, Spacelift adds a , out of the box and free of charge. You can thus ensure that your private modules are healthy before you distribute them to the rest of your organization. private module registry from HashiCorp full CI solution for Terraform modules 6) Effortless Setup and Customization If you manage a single or a handful of rarely changing projects, it’s likely that you just set your IaC up once and forget about it. But in a more dynamic environment, where microservices come and go, new environments proliferate and new product teams require their own Terraform workspaces. The need to configure it each and every time become a major nuisance, putting a lot of pressure on your DevOps team. Enter Spacelift. In Spacelift, much of the themselves—you can add Terraform and/or and mount files (even inject Terraform code!) programmatically or through the GUI without the need for administrative privileges or changing the central server configuration. For administrators, adding new projects requires minimal hassle since there’s no need to set up webhooks or change any YAML. And it can all be done programmatically using Terraform. configuration can be handled by the project owners environment variables 7) Programmatic Configuration What comes as a pleasant surprise to users of generic CI tools, Spacelift entities such as stacks, contexts, modules or policies can be managed in a declarative way using your favorite infra-as-code tool (this rule applies also to their configuration). Yes, that’s right— r that allows you to . Spacelift offers a Terraform provide programmatically manage the lifecycle of its own resources Administrative stacks get credential-less access to the subset of our that does not involve managing the actual infrastructure. For more sophisticated use cases, Spacelift allows you to generate API keys that are subject to the same access controls as normal users are, allowing you to create single-purpose tokens for restricted use by your internal scripts. GraphQL API 8) Drift Detection Generic IaC platforms do not provide any mechanisms to detect if your infrastructure is undergoing drift. Drift is a condition that represents the difference between the desired and the actual state of the infrastructure managed by your tool of choice – , , or another. Drift can be caused by either or a combination of changes directly introduced by external actors – either humans or machines (scripts) or via the dependency of your resources on external data sources. In any case, drift is not good. Terraform Pulumi CloudFormation Spacelift has got you covered here. You can configure periodic to , and take immediate action. You can even go a step further with optional automatic , ensuring your infrastructure always resembles your Terraform configuration. drift detection notify you whenever drift happens reconciliation 9) Resource Visualization General-purpose CI/CD platforms provide little to no insight into resource utilization from either a real-time or historical perspective. Which resources are over-or underutilized? Developers need to be able to intimately understand the material they’re working with. With regards to infra-as-code, the most important part of this story is understanding the managed resources in-depth. Both from the current perspective and through being able to put each resource in its historical context. The resources view in Spacelift gives you . With this deep insight into resources, DevOps are able to gain an understanding of the lifecycle of each resource managed by Spacelift and document it, regardless of the technology used — , , , or . greater visibility into each and every resource Terraform Terragrunt Pulumi CloudFormation Creature Comforts Last but not least, Spacelift puts an emphasis on great user experience, offering a myriad of creature comforts. for example allow you to attach entire collections of configuration to individual stacks and modules. provide a powerful audited way of running one-off administrative commands on an initialized Terraform environment – subject to their . allows a single individual to take exclusive control over a stack to ensure that nobody is able to modify its state while crucial changes are being made.

Each way is different in terms of complexity and offers a different set of features. It is important to keep in mind that choosing one way or another should be based on business and technical requirements. Most often, there is no point in implementing an in-house solution as the cost and effort of building and maintaining it may exceed its potential benefits. It is much easier and more efficient to leverage platforms such as Spacelift to provide these features for you instead. First Published here
